IMPROVEMENT IN HvDRAuLic-NozzLvEs.

The Schedule referred to in these Letters Patent and m'aking part of. the same.

the art or science to which it most nearly appertains to make and use myxsaid invention or improvements without further invention or experiment.

My invention relates both to the construction and method of operating the nozzles which aroused principally in hydraulic mining for directing a stream of water under great pressure against a bank or other deposit for the purpose of washing it down and exposing the underlying or gold-bearing stratums.

My invention consists- First, in connecting the nozzle with a water-chamber or distributer, from which the water issues'through a peculiar connecting-pipe into the nozzle Secondly, in certain improvements in constructing the nozzle, especially its interior, so that the stream of Water which.is forced through it will. be delivered without the twist given to' it when the ordinary nozzle is used; and

II'hirdly, in a novel manner of handling the nozzle, so as to change the direction and elevation ofthe stream according to the necessities ofthe case.

It also consists in constructing the entire machine so that it can beput together without the necessity of usingr bolts, rivets, or screws, thus avoiding the neoessityof transporting it in bulk, as it can be put together at the place where it is .to be used by any person without the necessity of other tools than a hammer. l

In order to describe my inventionso that others will be able to'understand its construction and operation, reference is had to the accompanying drawing forminga part of this specification, in which* A represents au iron chest or distributer, having at one side theanged opening a, to which the hose which conveys the water from the reservoir is'attached in the usualmanner, so as to deliver the water into the chest. j j

Other flanged openings b may be made upon the other two sides ot' this chest, to which other pipes may be attached when it is desired to increase the, pressurev inside the chamber above thatgiven by the main hose, or they may serve to draw oli the waterv from the chamber when it is desired either tol exhaust it or relieve .the pressure.

These holes or openings b, when not in use, are closed by valves, d, which fall across their faces -iuside the chamber, being held in place by gravity. The pressure of the water inside keeps them water-tight.

In the top of the chest Ais ka circular opening, of larger diameter than the main opening4 o, through .which the water -in the chamber inside the chest is driven by hydrostatic pressure into the nozzle, as will be hereafter described.

vThe nozzle is constructed' in two or more parts or sections. The rear section B has its rear' end closed by being cast in that manner, and has inletiopeuings, which pass througharms, e, at each side, into the interior of the section, thus forming hollow trunnions.

The hollow trunnions e bear against the opposite ends of a' horizontal pipe, D, which is bent to the form ofa 0. y

Rings or bands, f, are placed around the trunnions e previous to their being placed in theends of the curved pipe D, land keys g are driven between these bands and the section B, so as to bind them firmly against the ends of the pipe D, and Athus allow the nozzle to be moved up and down, while 'a perfectly water-tight joint is formed.

At the center of the C-shaped pipe D is a circular connecting-pipe or rim, h, which projects downward and passes through the circular opening inthe top of the chest A, a horizontal rim or iiauge on` its lower end retaining it in place and serving tov form a watertight-joint when acted upon by the pressure in the chest. A

The C-shaped pipe which carries the nozzle turns upon this joint from right to left'in giving a new di-l rection to the stream.

A vertical shaft, E, passes directly through the center of the chest A, being held by a nut beneath its bottom. This shaft also passes through the center of the pipe or rim h and G-shaped pipe D.

Just above where the shaft E passes thronghthe C-shapedpipe'D a washer, fi, is slipped over it, and a key or wedge, j, is passed through a slot in the shaft above it, and driven in until it presses downward upon the pipe D, thus relieving the moving joint in the top of the chest, so `that it will turn easily notwithstanding the inside pressure. v

The section F of the nozzle is usually made of great length, and is connected with the section B in the following manner:

Both sections B and F are provided with flanges, K, one of which is ,provided with slotted projecting lugs, l, which'pass through corresponding slots in the other flange.

A key or wedge, m, is then driven through the slot in the lug Z, which rmly binds them together.

nside of this section F are placed longitudinally three or more semi-circularV plates, n, which taper gradually toward the point of the nozzle. These plates carry the body of water in the pipe in adir-ect -line, and prevent 4the screw-like movement which is i to the section G by means of thelanges and keys, as

above described, and has an inside lining, p, which consists simply of a glass tube which tits inside of it. This lining will lallow the stream to issue with less friction than a metal-pipe, and can be renewed at any time without trouble. i

For operating the nozzle, I place upon the upper end of `the Ashaft or spindle E a dex-rick or crane, I, which isJ supported by guy-rods, J J, which are secured tothe top of the. chest and serve to keep it firmly in place. Y

A bifurcated bar, K, is secured to the section B of the nozzle, and has its separated arms extending up so as to pass upon each side of the boom L, so that, as the derck is turned from side to side, it will carry the` nozzle withl it;

A bevel-wheel, P, is secured upon the mast of the derrick, vwhicleugages with the bevel-wheel P', which hears in the cross-bar Q, and is operated by a crank, R, so that by simply turning the crank, the nozzle can be directed so as to throwthe stream to any de-v aired point.

The elevation and depression of the nozzle are accomplished bya. rope or cord, S, which is secured to mese it,'and passes up over a pulley in the extreme end of the boom L, thence it passes to a windlass, T, by turning which the nozzle can be given any desired elevation.

The entire machine is lput together withl keys entering slotted lugs, inthe same manner as described for uniting the nozzle sections, so that'it can be transported from place to place in pieces, and put together at the mine without diiiculty.

Having thus'described my invention,

What I claim, and desire to secure Aby Letters Patent, is

l. The combination of the C-shaped' pipe D with the chest A and section B, arranged, as described, to form a double-jointed connection between them, substantially as specified. Y

2. The combination of devices for 'connecting the two ends of the pipe D'to the pipe B, consisting of the loose trunnions e e, rings f f, and wedges g, ar ranged to operate as described,

3. The glassliningP, fitted in the nozzleH, by making it conical on the outside, and fitting its base against the end of the pipe G, to which the nozzle H is fastened. f 4. The arrangement of the conical guides n, upon the.V interior surface of the section F, substantially as and for the'purpose specified. i

In witness that the above-described invention is claimed by me I have hereuntoset my hand and seal.
